Browning 1297621 Connecting Link 80 Chain 1 Inch Pitch

Product Description

The BROWNING 1297621 is a connecting link designed for single-strand roller chain with a 1-inch pitch, conforming to ANSI Number 80 standards. It provides a reliable, field-removable connection point in roller chain drives, allowing technicians to close a chain loop or rejoin a chain after service without specialized tooling. The link is constructed from steel and uses a pin attachment type. With a roller diameter of 0.625 inches and a roller width of 0.625 inches, it is dimensionally matched to standard 80 chain and maintains drive integrity in industrial and mechanical power transmission applications.

This connecting link is used wherever ANSI 80 single-strand roller chain is installed in mechanical drive systems. Typical applications include conveyor drives, agricultural equipment, industrial machinery, and HVAC or refrigeration unit drive assemblies. It is installed and replaced by millwrights, maintenance technicians, and mechanical contractors performing chain drive service, adjustment, or replacement work.

Installation Notes

Installation and replacement of roller chain connecting links is typically performed by qualified millwrights or mechanical maintenance technicians. De-energize and lock out the drive system completely before removing or installing any chain components. Ensure the slip fit of the connecting link clip or pin is fully seated before returning the drive to service. Inspect surrounding chain for wear or damage any time a connecting link is replaced.
